A key feature of the Aadhaar number's generation is that it is a random number not based on any classification.
No Class-Based System: The Aadhaar number is generated randomly and does not contain any information about the individual, such as their religion, caste, income, or health.
Uniqueness: Its primary purpose is to serve as a unique identity. The random generation ensures that the number itself does not reveal any personal details about the holder.
Proof of Identity: The randomness of the number helps maintain privacy, as the number itself is only an identifier and not a source of any personal data. The link to an individual's information is maintained in a secure database by the UIDAI.
